About this study

Official title: NON-INTERVENTIONAL STUDY, MULTICENTRIC STUDY, AIMING AT CONSTITUTING A BIOLOGICAL SAMPLES COLLECTION FROM CENTENARIAN PEOPLE

The compositional analysis of commensal bacterial populations collected from a variety of clinical samples has been recently made possible with the availability of Next Generation Sequencing (NGS) technologies. The term 'next-generation probiotics' (NGP) is now widely used to describe these commensal species of potential health interest. However, this approach is still hampered by the fact that there are usually few or even no strains available for a number of commensal species. In this context, BIOASTER has developed a specific technological process based on flow cytometry analysis and then sorting under strictly anaerobic conditions to target and cultivate commensal species of interest.

The review of the literature shows that certain species present among centenarians have an interest in maintaining the longevity of these individuals. Numerous studies have shown that the intestinal microbiota of centenarians presents a greater diversity compared to groups of younger subjects as well as an enrichment in certain bacteria such as Akkermansia and Christensenella.

The goal of this observational study is to constitute a biological samples collection from centenarian people, to proceed with the isolation of beneficial commensal strains such as Faecalibacterium prausnitzii, Akkermansia muciniphila and Oscillospiraceae, in a non-limitative way.

Elderly and centenarian people will be recruited in nursing home among the Gerontopole of "Ile de France" network.

Blood (serum + TruCulture tubes) and stools will be collected from each subject.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Establishment of a bank of blood and faeces biological samples from centenarians people for research purposes

    Study will collect up to 18 mL of blood and minimum of 20g of faeces at one visit from people aged > 95 years.

    Measured: One day

Secondary outcomes (3)
  1. Bacteria collection

    Isolation and culture of bacteria of interest

    Measured: One day

  2. Fecal microbiota composition

    Measures of alpha and beta diversity of fecal samples

    Measured: One day

  3. Immuno-modulatory properties of isolated strains

    Cellular assays with immune related readout to decipher pro and/or anti inflammatory properties

    Measured: One day

Questions about this trial

What is this clinical trial studying?

An observational study of Healthy Aging, run by Bioaster at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 19 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Recruitment issues). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Establishment of a bank of blood and faeces biological samples from centenarians people for research purposes (time frame: One day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Mar 2024.
